How do I clean the bath?

Please talk me through how I clean a bath. Obviously I can get it done but feel I'm not doing it in the right way / with the right products. I'd ask my mum but she died and I can't ask my mother in law!!

If very dirty or limescale I use Vyakal spray, leave for 5 mins then rinse off wiping as I go with a rough cloth. Final wipe over with damp microfiber cloth.If not too bad, I use Method bathroom spray, same technique.
